Keir Starmer's party is being squeezed on all sides.

Reform UK has stretched its lead over Labour to six points, according to a new poll.

The YouGov survey shows support for the right-wing party stands at 28%, up two points on a month ago.

At the same time, backing for Labour has dropped by two points to 22%.

But while this will undoubtedly be a disappointment for Keir Starmer, it is where that previous Labour support has gone that may end up being a greater cause of concern.

Both the Lib Dems and the Greens have each enjoyed a one point increase in support, putting them on 16% and 12% respectively.

The data appears to back up the theory that Labour risks losing more support to parties on the left than it does to Reform UK and the Conservatives.

According to a new report by the More in Common think-tank, Labour has lost 7% of its 2024 general election vote to the Lib Dems, with a further 5% going to the Greens.

Combined, that is greater than the 11% of Labour voters who are now backing Reform.
